PATENT OFFICE.

COMBINATION STOVEPIPE THIMBLE AND COLLAR.

SPECIFICATION forming part of Letters Patent No. 747,334, dated December 15, 1903- Application filed January 23, 1903- Serial No. 140,323. (No model.)

lar, of which the following is a specification and description.

The object of the invention is to provide a thimble especially designed to securely clamp the st'ovepipe in the thimble, thereby eifectually securing the stovepipe in the thimble without use of wire, nails, &c., and to simplify the operation of putting up and taking down the stovepipe.

A further object is to provide a collar especially designed to operate the clamps that are connected to the thimble by turning either to the right or to the left on the thimble and, furthermore, to provide a body-plate by which the whole is held in combination and by which the thimble is made secure in its place in the flue.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

The several parts of the device may all be cast or some parts cast and other parts pressed from sheet metals. The same may be finished in japan, nickel, or enamels and may be cast in any degree of ornamentation.

Reference is to be had to the drawings forming a part of the specification, in which similar characters of reference indicate corresponding parts in the figures.

Figure 1 is a front elevation of the device.

Fig. 2 is a view with the body-plate A removed to show the clamping devices as they are when in place in the collar 0, the view being taken from the inner end of the thimble B. Fig. 3 is a side view of the body-plate A, collar C, and thimble B assembled in operative relation, parts being in section.

The thimble B is supported by the plate A by being riveted to it at the back. The-collar is supported by the thimble B and is held in 'place by the flange D. The collar is designed to revolve on the thimble.

The collar 0 is eccentrically constructed. By revolving it on the thimble it will force out the clamping devices which clamp the stovepipe when inserted in the thimble and which liberate the pipe when revolved the reverse, which allows the springs to draw back into the collar.

The device is secured to the flue by drilling into the brick and driving in wooden plugs and driving screws through the corners of the body-plate and into the plugs,thus thoroughly securing it to the flue.

Havingthus described my invention, what I claim as new and original, and desire to secure by Letters Patent, is

1. In a st-ovepipe-thimble, the combination of a thimble, a plate attached thereto and adapted to be secured to a support, a springsupported clamp and a rotatable collar carriedby said thimble; said collar being provided with a cam adapted to engage with said clamp.

2. In a stovepipe-thimble, the combination of a thimble, a plate attached thereto and adapted to be secured to a support, a plurality of spring-supported clamps and a rotatable collar carried by said thimble, said collar being provided with a plurality of cams adapted to engage with said clamps.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
